Abstract
We show that (in the description by rate equations) a laser with convention al optical feedback has the symmetry of any rotation of the electric field, whereas a laser with phase-conjugate feedback has the symmetry of only the rotations of the electric field over 0 and pi. This has important conseque nces for dynamics and bifurcations of these two laser systems. Most importa ntly, a PCF laser shows symmetry breaking and restoring bifurcations, somet hing that does not occur in a COF laser. (C) 2000 Elsevier Science B.V. All rights reserved.
